before everybody tells me the search function, I already have but I find mixed and contradiction answers on this issue. Some people say to do a full discharge followed by a full recharge as soon as you get the phone. Then on the other hand some people say that you shouldn't do this since the x1 uses a li-ion and its bad for it. Some people say you should charge it only when it's near empty, but on the other hand some people say to keep charging it as often as possible. Some say to take it off the charger once its fully charged, but then some say its ok to leave a fully charged battery on the charger.
As you can see, from searching the forum I've gotten pretty confused. so what is the PROPER way to charge our x1 battery? Is it also true that battery life gets better the more you put it on the charger? Does the x1i get better battery life than the x1a? I'm asking this because I'm gettin very poor battery life on my x1 compared to the 1-3 days of heavy usage that I see other people gettin on this forum. I'm going to exchange it today for a new one, so I don't want to make the same mistakes with charging my battery as I did with the first one.
Charging:
Do charge the battery often.
The battery lasts longer with partial rather than full discharges.
Discharging:
Avoid full cycle because of wear.
80% depth-of-discharge recommended.
Re- charge more often. Avoid full discharge.
Low voltage may cut off safety circuit.

that is very true......i get better life (3days) when i charge from 50%. otherwise i barely get more than 24hr.
thanks, that helps a lot! but what do I do once the battery has finished fully charging on the charger? should I take it off or is it fine to still leave it on the charger?
i have noticed this today,
i have installed a battery indicator bar (i cant remember which one) i charged my my X1 during night, when i woke up, i found that the phone is not charging and the battery is full. so i think that the phone automatically stopps charging when the battery reaches 100%
anyone can confirm that?
Not sure about the way to charge it, but i can comment on your current battery life. when i got mine, i had 1 days battery life, but after flashing it, i'm now getting between 3-4 days......

Glad to see that there are people that read the "real" stuff (I'm talking about dogans), the batteryuniversity site is mantained by the very battery fabricants, so their opinions are the best informed ones, even if they might bias a little to keep the bussiness "healthy".
However, any Lithium battery should not be fully discharged -at least not often-, because the full discharge shortens their life.
Usually, good chargers do control the charging parameters (battery's voltage, current and temperature curves) while it charges and "know" when to stop, even if they really don't stop ever (normally), the go in "tickle" charging mode, to keep the battery "fully" charged.
Hope this helps.
The article on Wikipedia about Li-Ion batteries is quite informative as well:
http://en.wikipedia.org/wiki/Lithium_ion_battery
It specifies the technology, the do's, the dont's and usefull tips in keeping your battery in good condition.
At the office I leave my phone in a cradle. When I get calls I remove the phone to answer and then return it to the cradle when done. My battery goes from 100% down to somewhere in the 90's then charges back to 100% in the cradle. Does this repeated process harm the battery in any way? I've read that these batteries don't suffer from the memory effect, but I'm still not sure if this counts as a charging cycle.

You should always let the battery run down completely some times maybe once a week.
Really? I've read on this forum that there is no need to do that with the new Lithium Ion batteries. I've even read that this could have a negative effect and you should try not to let the battery drain completly.
I don't understand why there isn't a proper battery care section in the manual. Its as if its some kind of voodoo science.
Perhaps not Once a week. But Once a "while"
The reason is that, Phone software uses approximation to calculate the charge left in the Battery. So over time, battery ages and software may not be calibrated to match with the battery's storage capacity. So draining the battery entirely and charging them fully gives the phone's software to assess the battery's health and recalibrate.
It's a lithium battery mate. The only way you can really damage it is by a complete discharge. So long as you don't switch the phone back on once it switches itself off due to low battery you needn't worry about anything else.
Also in theory the lithium batteries have a lifespan of say about a 1000 charges for example and everytime you charge it has one charging less left. This ofcourse isn't exactly how it is in practice but charging the battery alot wears it down. It isn't good either to keep it in the charger for a longer time after it's reached a 100%.
Hi,
this is only partly correct:
Suppose the battery can make 1000 (which I don't believe) charge cycles,
it means that you can charge 1000 times from empty to full.
If you just charge 1000 times from 50% empty to full it counts for 500 cycles!
So,
don't worry, let it stay in the cradle if you like
There are 500 opinions about that but believe, as I wrote is correct.
Theo
Yes, what I said wasn't exact science and I used 1000 cycles as an example, but from what I've read it is better to let the battery drain to less than 50% and then charge it full rather than charge 5% at a time. My previous post was meant to illustrate this.

That's a load of crap, no offense... Lithium batteries have no memory effect and have absolutely no need to be completely discharged, that's a ancient thing from the time of nickel-metal hybrid batteries. The only actual reason for full charge cycles is to calibrate the device for that exact battery.
Keeping a lithium-ion battery in a charger most of the time will wear the battery down faster than getting it drain more and then charging it. Keeping the battery almost fully loaded/in a constant loading state wears the battery capacity by approximately 20% a year (can't recall the source/study just now)(EDIT: and my personal experience is that the battery capacity will wear that much anyway, no matter how you use it). The life-cycle of phones these days are roughly two years nowadays so IMO you can keep it in a cradle with no worries, if you wish. And lets face it, a new battery after a year of usage won't be that big an investment after all.
To add to the above post, running down a lithium battery completely does more damage than benefit. This is almost impossible though with normal use as the phone shuts down long before the battery is completely empty
Is this the definitive way to do it?
http://hemorrdroids.net/battery-calibration/
Those steps came from here, xda devs.
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6 **Root users only** Using a Terminal Emulator, type “su” enter, followed by “rm /data/system/batterystats.bin”
7. Run the device’s battery down until it turns itself off.
8 .Turn the device on and charge for at least 8 hours.
9. Unplug the device, turn off, then charge for another hour.
10. Unplug the device, turn on, wait 2 minutes.
11.Turn off again and charge for another hour.
12. Restart and use as normal.
Quite a performance! Does it preserve battery lifespan, or is it more to do with slowing down battery drain and does it really work?
He mentions 2 interesting things:
"Generally charge them before they get lower than 50%". I didn't know that, so it's actually better to charge more often and not let it drain down?
"USB charging is actually better for the battery and you may get up to 1 hours more standby time." So you gain an hour standby but it takes twice as long to charge the phone.
Nice manual
Will try it

Some will say that its complete nonsense .
Overcharge for 8 hours ??? how does the battery not turn charging off at 100%
Recharge 50% the accepted figure is not to go below 20% to often .
They may be right or wrong their are so many contrasting views on battery charging .
jje
Discharging battery and then reloading it fully, it's the normal procedure for battery calibration for almost all the devices in the world (including computers, etc.).
Step 8 to 11 seems quite a bit strange however.
hm, just seen a different way to calibrate the battery. basically, you drain the battery, take it out for a couple of minutes, put back in, then try to turn it on to make sure it's completely flat.
then you charge it fully, then boot to recovery and wipe battery stats then drain and fully charge. so... which one is more likely to be the better?
that guy also advises to repeat that 12 step, 1-2 day long tedious procedure "every month or so".
it is lunacy honestly speaking
does it work? did he died ?
LOL I dont understand .... I just read in another day that NEVER LET BATTERY GO LOWER THAN 15% and know I read "drain drain drain" Oh welll ...
I also thought that at 100% the charging process stops.
Although this thread is about battery calibration, these questions about battery charging always pop up.
Battery calibration is the process by which you set your device with your battery data.
Every single battery is slightly different. Although there are minimum stantards to every spec of the battery, each battery is different.
Calibrating your battery is nothing more than setting your phone to the real specs of your own battery (since the phone comes configured with the battery factory standards). For example, your phone may be set to use a battery which maximum charge is 1650 mAh, but your battery has a maximum charge of 1625 mAh. That may be within the acceptable factory standard, meaning you have a normal battery, but that also means that your phone will never indicate a 100% charge after you unplug the charger.
If you calibrate that hypothetical battery, you will "tell" your phone that its maximum charge capacity is actually 1625 mAh, meaning from that on your phone's battery indicator will be more accurate.
For that reason, it is necessary to fully discharge and fully recharge your battery for the calibration process, since your device must read the actual specs (minimum charge, maximum charge, charging current, etc) of the installed battery.
I don't know about how many times this full cicle (discharging and recharging) must be performed, but that is the reason why it must be performed for the calibration to succed.
A DIFFERENT THING is the normal discharging and charging process during normal use of the phone.
In this case, you should NEVER let your battery go under 20% and, what few people know, it also should never go over 95%. This stresses the battery and diminish its life time.
Also, and there's a lot of doubts about this, the lower the charging voltage, the slower the charging process, but the longer the battery life.
High charging voltages (like the one used by the charger sold with the phone, which is around 5V) stress the battery, diminishing considerably its life time.
That is true for all lithium-ion batteries!
Therefore it is better to charge your phone through USB (which uses around 4,3V) than to do it using the charger provided with the phone.
You may be asking "If the charging voltage of the charger provided by the manufacturer stresses the battery, why does the manufacturer provide such charger?"
For purely commercial reasons! Higher voltages mean shorter charging cycles, which please the consummer. Moreover, the battery capacity loss with the factory provided charger is around 15-20% a year (considering "normal" to "heavy" use). That is to say that after a year your battery will only reach 80-85% of the maximum charge it used to reach when it was new. And by that time your manufacturer expects you to consider buying a new phone, with more features.
Summing it up:
- calibration is just the process by which you "tell" your phone what the real specs of your battery;
- in normal use, charging your phone through USB is better than doing it with the manufacturer provided charger;
- try not to let your battery charge go under 20% nor above 95%;

Spin three times in clockwise direction with left middle finger on your nose while blinking your eyes with the phone plugged in.
Jump in the air 3 times.
Unplug phone.
Thats some messed up instructions.
Do you have any idea what kind of strain you're putting on the battery while doing all that?
All you're gonna get is some extra minutes, maybe an hour but is it really worth it because you're just reducing overall battery lifespan by doing that procedure over and over.
Specially when you constantly keep the battery at 4200mV (full charge) for a long time. You're practically killing it by overcharging.

Never done a calibration on a battery and most of the time i even didn't let battery to discarge very much and then load it again. Never had a problem with battery life it last how long it should last every time and i've used that battery for years. So the battery "calibration" are kinda useless.

The way I would calibrate my batteries is a bit different. Lithium ion batteries don't need to be drained then charged to full AFAIK, and I even remember reading somewhere that draining it is actually only for NiCad batteries. It used to be relevant when phones were using NiCad but not anymore.
Read: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
As such I have read that the universal way to 'calibrate' batteries is by charging to full, using for a couple of mins and charging again.
What I have been doing is:
1. Charge to full when phone is switched off (doesn't matter if it's from 0% or 99%).
2. Switch on the phone, use for 5 mins.
3. Switch off then charge until full.
4. Repeat step 2 once more
That's it! It seems pretty simple but it seems to have worked for me.
The way i do it is different. Firstly i have the battery calibration app from the market by Nema..then i fully charge my phone and when it says its fully charge i go into the app. There it gives me the instructions on how to calibrate...First i wait till i charge the phone without any interruptions. then click on the app and wait til the battery goes to 4200MV and then i press the calibrate button and then the app does it for me. Then i drain the battery again without any interuptions or breaks during that time and then charge it again once battery dies down and thats it.
there are so many ways being touted on the forums you really dont know which one to go for...but whatever works for each person then who are we to tell someone different just thought i share that
If my battery dies, or gets significally lower capacity after 1 or 2 years of usage, I'll just buy a new one if I plan to keep the phone longer.. Going through these rituals and painstakenly monitor my battery % so that it never goes below 20 % or above 95 % is just not worth it.. Doesn't increase the life THAT much anyway.. I use the phone until I hear the beep for low batt, and from there until I have a charger available.. Most of the time it's before it reaches 10 %, thats good enough for me.. Once in a while it might even go so far that it dies.. Then I charge it till it says 100 %.. Most of the times I plug it when going to bed, and let it charge over night.. This is normal usage and what the battery should be designed to handle, and so far it does..
I just found this very interesting article, maybe you'll like it too:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Short summary:
1. "A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life."
2. "Higher charge voltages boost capacity but lower cycle life and compromise safety."
its also suggested that you let your phone go through one complete discharge from 100 - 0% at least once a month.
- also on the heat front mentioned in the OP, i take it that means its best to remove your cover when charging your phone to stop a build up of heat?
You mean taking of the case, like Otterbox?
No, I wouldn't do so because my battery never gets warmer than 26-29 degrees.
Bad would be everything above 30°.

Our electronic profs at uni (who actually know what they are talking about) told us to keep the charge between 80% and 30%. Discharging to 0% only harms the battery.
So i'd really like to know where it's suggested that you should discharge to 0% once a month.
btw: This is a quote from the link from the op:
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses."
So i'd say that discharging to 0% once a month is nonsense and only harms your battery
I read that a while ago on the iPhone support website and did that for my old 3g, I just kept the practice running when I got my DHD. I guess either Apple is wrong or its only usefull for non-removable batterirs.

That's probably why their batteries died so fast.
gotta voice in here. i've also heard that its optimal to keep your battery in the 80%-30% range. and that its only damaging to fully drain your battery.
but on the flip side, its kinda needed to do a wipe battery stats once in a while, so i can get a better reading of my battery.... was a time when i hadn't done it for ages, and i was at 1% battery while watching a movie for 30 minutes..
so, I recommend at least, to DONT drain your battery.. but if you are getting really off readings on your battery. do the wipe battery stats thing
My DHD battery seems to be getting worse and not holding its charge. as it's almost been 18 months I decided to buy a new OEM battery and I was jus wondering how should I run the 1st few cycles? And how long will it take to reach its optimum capacity? Also will I need to wipe battery stats and calibrate it?

Suggested initial full charging/discharging cycles are ONLY made to train your phone and NOT your battery and in most cases aren't even intended for current android phones.
Those mythical suggestions are often based on facts for non-lithium rechargable batteries.
Nowadays rechargable lithium batteries are often shipped at least half full. So what you can and should do is just use the battery and try keeping it between 30% and 80%. That's all you have to do.

So are you saying i shouldn't even charge it to 100% and what about the recommended monthly full charge to complete discharge to calibrate the battery?
Well you can charge it to 100% if you want. That will reset the battery log of your phone, so it can't hurt that much.
But charging it for an extensive amount of time will bring you no good. The charging circuit in your phone and in general the charging circuit used to charge lithium-ion batteries will stop charging once the battery is full. That way it prevents the battery from overcharging. But it also means that charging your phone for any more time than it needs to won't make it run any longer.
The monthly complete discharge is not to calibrate your battery as i've allready stated. It is used by the phone to better estimate how much power your battery can currently hold. So in a sense it's used to calibrate but not the battery itself but the battery statistics in your phone.
The phone knows how much energy the wall-charger provides and can thus determin huch much power is stored in the battery once it hits 100% (or better: reaches it's maximum voltage). If you have a charge from 1% to 100% then the phone can obviously determin the battery's capacity more accurately than if you charge it from 50% to 100%.
/edit:
And yes. If you really want to prolong your batteries life then keep it's charge between 80% and 30%.
But just see to it that the charge is above 30% and you're good.

beats me^^
My point was that the calibration is done for the accuracy of the percentage displayed and not to make your battery hold more energy, regardless of what phone/device you use.
And i'm using Battery Monitor Widget so i tend to mean that when i talk about the "historical data". Because BMW really does tell you to run larger charge cycles to increase accuracy. It however doesn't tell you that constantly running your battery down to 0% will only shorten it's lifetime.
Dear readers,
I am going to buy a new battery for my HD2 but there is a problem.
I would need to train the new battery and charge it full the first time without turning on the HD2 right?
How can i do this when my HD2 keeps turning on by itself? I even think my phone charges when it is off?
My phone runs ics 4 with magldr.
Can anyone help me out?
Just drain the battery normally and charge it when you sleep?
Draining a new battery will make it unusable???
No it will be fine, Li-ion are quite durable & do not have charge state preferences.
Just buy a new battery & put it in your HD2 & use it normally, if charge very low when first turn it on > plug it in & charge to full.
Then why do people and retailers keep advising me to fully charge batteries before first use?
Cause batteries don't come fully charged?!
But if you charge it first how do you know the battery is fully charged without draining it first since battery stats are incorrect?
Hmmm, i have been told that fully charging it at the first time before first use gives u better battery performance and better battery stats. U are telling me the opposite thing lol? You could see it is full by the constant green led? But if it is like you are telling me then that indication would be false?? Do i get it right?
A new batteries capacity should increase after first few cycles as will devices calibration of the new cell.
The Battery itself is dumb & you can use what method you like really with li-ion cells to charge them.
Only issue sometimes seen is devices recognition of cell power level is not shown correctly.
Have recently issued 20 new cells for our HD2 fleet, staff use them as they needed & without stringent charge routines & all is fine.
A little common sense is all that is needed & maybe calibration reset if a problem appears.

Hmmm, i have been told that fully charging it at the first time before first use gives u better battery performance and better battery stats. U are telling me the opposite thing lol? You could see it is full by the constant green led? But if it is like you are telling me then that indication would be false?? Do i get it right?

What if you get a fake/defective battery that only holds 40% capacity and reports that as 80% and you charge the battery to report 100% (which activates the green led). How would you find out that this battery is holding a real 100% charge without draining it first?
With an app that shows u the amount of mAh?
Or is that impossible?
Any app calculating mAh will need a few cycles of the battery to give an accurate estimate. Reading any data direct from a cell is pointless as the cheap cells use chips to display false capacities.
In your circumstances just install new battery & charge while device is on then charge as required & only worry if run time seems very bad.

Now thats major bull. No app can give 100% correct info about battery capacity.
The only one method of correctly defining battery capacity is by using computerized battery analyzer.
If you want to get most of your new battery(Li-ion/poly):
-first make several charge/discharge cycles(after 5-10 you will get desired OEM capacity)
-charge it with wall charger, do not charge through USB
-charge it whenever you can, even if few % are only used
-avoid complete battery discharge(Lithium cells hate complete discharge!)
-keep it at reasonable temperatures, dry
-and don't buy cheap/promising alternatives. Only OEMs are worth buying. Forget about Mugen Magic(proof: www.batteryboss.org)
Battery apps are not always acurrate. They only measure in certain intervals (and then estimate the other stats), which only tells you the current in that instantance of time and the rest is ignored. Also if you undervolt, sometimes the drain measured higher than usual and the battery percentage becomes erractic (ie increasing after a reboot) that will easily change the estimated capacity.
